Brief summary

The purpose of this study is to test the body's response to several doses of two different inhalation products in healthy volunteers.

Detailed description

Healthy subjects will be enrolled and will receive 2, 6, and 12 inhalations from both the test and reference pMDI products according to a six-period cross-over design. Electrocardiograms (ECGs) and plasma potassium and glucose levels will be measured pre-dose and over 6 hours post-dose.

Outcome results

Primary

Relative Potency Max Heart Rate

Selection of steepest part of dose response curve for Relative Potency: 6 and 12 inhalation dose pairs. Slope of B and C line compared with slope of E and F to obtain relative potency value. Two inhalation dose not utilized as not on steepest part of curve.

Time frame: Baseline, up to 6 hrs

Population: relative potency calculated for dose pairs B (6 inhalations) and C (12 inhalations), compared with E (6 inhalations) and F (12 inhalations)

ArmMeasureValue (NUMBER)
Test B and C vs Reference E and FRelative Potency Max Heart Rate0.8619 unitless
Comparison: The measurement of relative potency was conducted for the pair of doses which met the above criteria and lay on the steepest linear portion of the dose response curve. The log estimate of relative potency was obtained as the ratio of the estimated treatment effect as measured by the difference in the intercepts of the parallel lines divided by the estimate of the common slope for log dose.p-value: >0.190% CI: [0.67, 1.5]ANOVA
